Retaining Wall Stability Computation Sheet 2.05 Developed by J. M. Duncan and R.L. Mokwa, October 1998 Change only those values shown in red. Other cells are locked. Revised by B. Yang and J. M. Duncan, May, 2002 Project: Problem 1 Calculated by: Jesse Siegel Date: 3/18/2008 For wall dimensions, loads, and properties Include surcharge over b h ? No f c ' = 3,000 psi f y = 60,000 psi D f = 1.5 ft ρ / ρ b = 0.45 h w = 10.5 ft i = 0 deg. Calculated Backfill γ eq = 45 pcf b h = 4.00 ft Backfill γ bf = 113 pcf H = 12.00 ft Surcharge q s = 250 psf E h1 = 1,200 lbs/ft K s = 0.40 E h2 = 3,240 lbs/ft μ = 0.73 E h = 4,440 lbs/ft y/H = 0.33 E v = 0 lbs/ft K v = 0.00 W bf = 4,725 lbs/ft B = 8.50 ft W f = 1,913 lbs/ft b t = 2.50 ft W s = 2,756 lbs/ft t 1 = 2.00 ft W k = 0 lbs/ft t 2 = 1.50 ft W f f = 0 lbs/ft d = 1.50 ft y = 4.00 ft x 1 = 3.62 ft Properties of soil in front of key x 2 = 6.50 ft γ = 130 pcf x 3 = 3.50 ft c' = 0 psf N = 9,394 lbs/ft φ ' = 36 deg T = 4,440 lbs/ft x = 3.05 ft Depth of key below footing q = 1,540 psf Notes: 1. P p = passive pressure resisting force. Passive resistance is only D k = 0.00 ft Pp= 0 lb/ft included for the soil in front of a key, that is, only over the depth D k .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
